What is Contractbook?
Contractbook hands the AI's extraction prompts over to the customer
Contractbook publishes short, emoji-headed notes, most of them arriving in same-day batches. The August 3 batch covered admin permission maps across spaces, OTP two-factor at login, calculations inside forms, a rebuilt search results page, and a new model behind AI data extraction. This release opens the default data fields themselves: the prompts behind each AI-detected field can be rewritten or renamed per contract type.
What is SiYuan?
SiYuan enters a rapid alpha sprint, shipping calendar upgrades, transitive backlinks, and export extensions daily.
SiYuan is deep in pre-release iteration for v3.8.6, pushing multiple alpha builds per day. Recent work lands in three areas: calendar and scheduling (ISO week numbers, undated task scheduling, inbox-to-document insertion), knowledge graph depth (transitive backlink display, global reference sorting), and editor ergonomics (Markdown parsing performance, memory efficiency on long documents, customizable context menu shortcuts). The product continues to target power users who want local-first data ownership with a dense feature surface.

Contractbook hands the AI's extraction prompts over to the customer
◆ Current state
Contractbook publishes short, emoji-headed notes, most of them arriving in same-day batches. The August 3 batch covered admin permission maps across spaces, OTP two-factor at login, calculations inside forms, a rebuilt search results page, and a new model behind AI data extraction. This release opens the default data fields themselves: the prompts behind each AI-detected field can be rewritten or renamed per contract type.
◆ Where it's heading
The AI extraction layer has been treated as a black box that Contractbook tunes and customers accept. Editable prompts break that — accuracy on a customer's own contract vocabulary becomes something they adjust rather than file a ticket about. It fits the wider pattern of the last few releases, where admin surfaces (space access maps, group permissions, contract-type management) are being built so companies can configure what used to be product defaults.
◆ Prediction
Once prompts are editable per contract type, per-field extraction quality becomes visible and arguable, so expect some form of confidence indicator or review step on extracted data next.
SiYuan
6.3COLLAB
SiYuan enters a rapid alpha sprint, shipping calendar upgrades, transitive backlinks, and export extensions daily.
◆ Current state
SiYuan is deep in pre-release iteration for v3.8.6, pushing multiple alpha builds per day. Recent work lands in three areas: calendar and scheduling (ISO week numbers, undated task scheduling, inbox-to-document insertion), knowledge graph depth (transitive backlink display, global reference sorting), and editor ergonomics (Markdown parsing performance, memory efficiency on long documents, customizable context menu shortcuts). The product continues to target power users who want local-first data ownership with a dense feature surface.
◆ Where it's heading
The v3.8.6 alpha cadence points to a stable release within days. Simultaneous effort on export fidelity (JavaScript embeds in PDF and image output), calendar promotion from visualization to scheduling tool, and AI agent capabilities (TypeSafe decision models visible in beta builds) suggests SiYuan is converging its PKM core with structured personal workflow management. The mobile editor is also receiving parity work alongside desktop.
◆ Prediction
The v3.8.6 stable release is the immediate next step given the alpha pace. A more deliberate announcement around the AI agent decision model integration — first surfaced quietly in the beta channel — is the likely follow-on, as it represents the most directional capability added in this cycle.
